The house was all but finished, Sue walked past the pool with a cup. She was wearing a robe. It was Friday afternoon and her target was the last man to leave, he was inspecting the work before signing it off. I could not hear what they were saying. I could see a lot of what they were doing. The man took the cup. It was not long before Sue let her robe fall open and closed in. Her hand dropped to his belt. He stopped drinking. Sue fell to her knees and took his cock into her mouth. He had the cup in his hand and no where to put it. He wrapped one hand around her neck. Sue was bobbing his cock. I was standing at my bedroom window, my hand wrapped around my cock, wanking. By the pool Sue was sucking on cock. In the window I crossed my legs and clenched them. I came over the window. By the pool Sue had dropped her robe. The man was pulling his kit off. She sat him on the end of the diving board. She was not going to use a condom. I picked up a string of condoms from my bedside table. Wrapped a rubber band around them and tossed them across the pool. Sue looked up, she saw me, and I waved. I do not know if he even noticed. Sue rolled the condom on and spread her legs over the man. She sank onto his member and started to move. I started to wank again. I knew she could see me and she pushed him away from her. Still riding him she let me see more. I came spunk flying out the window. The man came but Sue kept moving. When she finished she handed his tea cup back and walked away from him, the slut. Suddenly, he was alone his shaft deflating, a loose condom and confused. Sue came straight up to by room. I was still at the window when the door opened. Sue joined me, looking out the window at the man. “Have you got a discount” I asked her. “May be” she said as I pushed her shoulders down. She rested her hands on the window sill. I pushed my cock into her pussy from behind. Her hot and well worked pussy was warm and wet. I did not fuck her hard; I did not want her slipping out the window. She was looking at the man getting dressed. I was looking over her. He looked up as he drank from the cup. Sue’s tits were dangling out the window. He must have known I was shafting her. Sue called out “Call me honey.” The man just looked up at us.
